Cannot validate concrete class

[shadowhand]

Because of this constraint it is not possible to validate an object that has a concrete class, even if the class looks something like:

class User
{
    public $id;
    public $username;
    public $email;
}

Shouldn't this constraint be $ok = is_object($data); ?

The reason to limit objects to \stdClass was safety and performance of (array)$obj casting, though now I think it is not enough to drop class objects support.

Thank you for pointing the issue.

Fixed in v0.12.5.
